Signs Your Furnace Needs a Tune-Up Now

  • It’s been more than a year since the last tune-up

Frequently Asked Questions

Is a furnace tune-up worth it?

Yes. A $99–$149 tune-up that catches a $50 ignitor problem prevents a $200–$400 emergency call in January. Plus, a well-tuned furnace runs 5–15% more efficiently.

How long does a furnace tune-up take?

60–90 minutes for a typical Denver Metro furnace. We give you a window and call ahead when we’re on our way.

Do I need a tune-up on a new furnace?

After year one, yes. The manufacturer warranty typically requires documented annual maintenance. Skipping tune-ups can void your warranty claim.
